Nergal was an outcast archdevil exiled by Asmodeus to Avernus.[1]

In an attempt to learn the secrets of silver fire, he captured Elminster whilst the wizard was in Avernus and exhausted from sealing a planar rift between Avernus and Shadowdale. Nergal subjected Elminster to horrific suffering, all the while stealing his memories using a mental link, until Nergal's body was destroyed by the Simbul (his life-force seemingly escaped).[1]
